Travel Alarm Clock - No Bells, No Whistles, Battery Operated, Alarm, Snooze, Light, Black WHILST MOST TRAVEL CLOCKS on the market make a constant ticking sound and have very cumbersome controls, our customers told us they need a silent clock, and one that is easy to switch on/off the alarm. So, we listened, and redesigned the generic model based on two years customer feedback. ALARM AND SNOOZE - The alarm is loud and rings until turned off. The snooze allows the alarm to ring every 5 minutes until switched off. You will never sleep through the Travelwey Alarm Clock! LUMINOUS HANDS PLUS LIGHT ON DEMAND - If the analog clock is exposed to strong sunlight during the day the luminous hands and digits will glow in darkness for up to 4 hours. For longer periods, just a quick tap on the clocks top button and the full clock face will illuminate. HARD PLASTIC CASING, BATTERY OPERATED - Don't worry if this clock is dropped. The hard plastic casing makes this clock very durable. Ideal when travelling or equally perfect for a desk or bedroom. The desktop alarm clock is battery operated, single AA. NEW TRAVEL LOCK - No need to remove the battery when travelling, the convenient travel lock ensures the top button is not pressed in your luggage which would otherwise activate the light and drain the battery.
